Bingo... Marketing analysts have proven many times over that the word "SALE" brings an actual euphoria or happiness to people, and a single "SALE" sign in a window will double the traffic into a B&M!
Big retailers like Walmart, and especially Best Buy... whoa... they never have what they advertise on sale, but are really quick to push you to something "similar" at twice the price...or something cheaply-made for only $5 more than the "good" product on sale...
Retail America is truly an impulse-buy, feel-good lot of consumers....
